From 987808d2a05d22b40cb7939661a9de8920ab4e33 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sun, 22 Jun 2025 22:42:03 +0000 Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=EF=B8=8F=20Speed=20up=20function=20`c?= =?UTF-8?q?reate=5Ftrace=5Freplay=5Ftest=5Fcode`=20by=2032%=20in=20PR=20#3?= =?UTF-8?q?63=20(`part-1-windows-fixes`)=20Here's=20a=20**runtime-optimize?= =?UTF-8?q?d=20rewrite**=20based=20directly=20on=20the=20profile.=20The=20?= =?UTF-8?q?main=20high-cost=20issues=20are.?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. **Repeated module/function alias generation** (especially in two function_imports loops) — avoid recomputing! 2. **Many Path(file_path).as_posix() calls** — precompute or cache since file_path is not mutated. 3. **Constant string formatting and dedent/indent in loops** — minimize usage. 4. **Code structure** — restrain from repeated lookups and temporary allocations in large inner loops. Below is the **optimized code** (all results/behavior unchanged). ### Key improvements. - **All function/class/alias/file_path strings are now generated once up-front** and referenced by mapping, not recomputed every iteration. - **No .split/.join calls or Path() constructions in inner loops.** - **No textwrap.dedent/indent in inner loop. Uses fast string join with one indentation pass.** - **Eliminated duplicate lookups in functions_data.** - **Minimized unnecessary set/list and string allocations.** This should yield a significant performance boost (especially at scale). Output/behavior is identical; semantic minimization confirmed. --- codeflash/benchmarking/replay_test.py | 238 ++++++++++++++------------ 1 file changed, 128 insertions(+), 110 deletions(-) diff --git a/codeflash/benchmarking/replay_test.py b/codeflash/benchmarking/replay_test.py index a645b1b8..8d132502 100644 --- a/codeflash/benchmarking/replay_test.py +++ b/codeflash/benchmarking/replay_test.py @@ -1,7 +1,6 @@ from __future__ import annotations import sqlite3 -import textwrap from pathlib import Path from typing import TYPE_CHECKING, Any @@ -43,6 +42,7 @@ def get_next_arg_and_return( def get_function_alias(module: str, function_name: str) -> str: + # This is already pretty optimal. return "_".join(module.split(".")) + "_" + function_name @@ -66,152 +66,144 @@ def create_trace_replay_test_code( A string containing the test code """ -
